BACnet Gateway – Version 3 - Functional Specification CB02A125 1

1. Summary In response to the requests from the equipment (BACnet client) considered as a central monitoring panel which

supports BACnet-ANSI/ASHRAE135 protocol, the BACnet Gateway actuates as a BACnet server that replies the status information of air conditioners connected to DIII-NET and receives the setting commands to air conditioners through the service specified by BACnet.

2. Configuration of connection A BACnet client that supports BACnet-ANSI/ASHRAE135 protocol allows direct connection via generally used HUBs

such as Ethernet. The image of its connection configuration is as shown below

Remote Controller Group

9. Report Function

9.1. COV Notification A request for COV registration is accepted through the SubscribeCOV service. (1) Settings of Confirmed or Unconfirmed COV

This item is supported according to the BACnet Specifications. (2) Settings of the desired lifetime of the subscriptiom

This item is supported according to the BACnet Specifications. When COV notification is made at the time of status change, the difference between the registered time and present

time will be calculated. If the difference is greater than the registered lifetime of the subscriptiom, the subscriptiom will be judged expired and deleted. Therefore, if a clock time change is made, the lifetime of the subscriptiom may differ from the value that has been set. (3) Memory after Interruption of Power Supply to System

This item is not supported. Registration information is not stored in the memory, and will be lost when the power is turned off. According to the BACnet Specifications, It is not required to garanttee preservation of subscriptions across power

failure. (4) Registration Information of Notification Destination

This item cannot be viewed from the BACnet. Network visibility is not guaranteed according to the BACnet Specifications. (5) Number of Subscriptions

Up to 10 clients can be registered for each object. The following error message will be returned if an attempt is made to subscribe more clients. Error Class = RESOURCE; Error Code = OTHER

All objects of the air conditioner support COV notification.



9.2. Event Notification Only Intrinsic Reportiong is supported as Event notification.

9.2.1. Registration Information on Event Notification Destination A single Notification Class object is generated, and all objects supporting Intrinsic notification refers to it. Therefore, if a notification destination is registered with the Notification Class object, Events from all objects will be notified.

(1) Notification Class Instance Number

This item is fixed at 3. (2) Priority This item is always fixed at 255. (3) Ack_Required This item is always fixed at FALSE. (No AcknowledgeAlarm service is expected for any Event.)

9.2.2. Registration of Event Notification Destination It is possible to use the AddListElement service to register notification destination information on the Recipient_List

property of the Notification Class object. Details of the BACnetDestination, notification destination information to be registered, are as per the following.

(1) Valid Date This item conforms to the BACnet specifications. Event notification is enabled or disabled according to the specified

day of the week. (2) Valid Time

This item conforms to the BACnet specifications. Event notification is enabled or disabled according to the specified time range. (3) Process ID

This item conforms to the BACnet specifications. Event notification is made with the process ID registered. (4) Notification Destination Address Information

This item conforms to the BACnet specifications. It is possible to specify either Device object ID or BACnetAddress. When the Device object ID is specified, it is necessary to know the relationship between the Device object ID and

BACnetAddress before Event notification is made through a service such as the I-Am service. Information on the relationship will be stored in the Device_Address_Binding of the Device object.

When the system starts, the process to transmit the Who-Is service and receive the I-Am service will be performed. If the information is insufficient for some reason, no Event notification will be made.

If no BACnet packets are received from the counterpart for 10 minutes, the BACnet device will be deemed disconnected from the network. If the I-Am service is not received after that, the Device object ID will be indefinite, and Event notification will not be made to the notification destination where the Device object ID is specified. (5) Issue Confirmed Notification

This item conforms to the BACnet specifications. Registration is possible with or without confirmation. (6) Transitions

The value is kept on hold, but ignored at the time of processing. (7) Maximum Number of Notification Destinations to be Registered

It is limited to a maximum of 10 clients. The following error message will be returned if an attempt is made to register more destinations. Error Class = RESOURCE; Error Code = OTHER

9.2.3. Deletion of Event Notification Destination The RemoveListElement service can be used to delete notification destination information from the Notification Class

object. The existence of registration is judged by checking the coincidence of both process ID and notification destination address information. Unless the process ID coincides, the same notification destination address information will not be deleted.

9.2.4. Event Notification Destination Re-registration If an Event with the same process ID and notification destination address information is re-registered, the existing



registration destination information will be overwritten. Therefore, information items, such as the valid date, time and whether it is with or without confirmation, will be refreshed.

9.2.5. Event Notification Destination in Memory The registered event notification destination is stored in the memory. When the system is turned on, the event

notification destination will be initialized with the stored information. The Event notification destination will be stored five seconds after the registration or deletion.

9.2.6. Event Confirmation Event conformation actions specified by the BACnet are not supported. Instead, the following specifications will apply. (1) The AcknowledgeAlarm service is not supported. (2) The Ack_Required items of the Notification Class object are all fixed at FALSE. (3) The Ack_Transition items of the Event local object are all fixed at TRUE. With consideration of Events that occur while the counterpart device is offline or disconnected from the network, the

time stamp of the occurrence of each Event will be kept on hold. This will not be guaranteed in the event of a power interruption. The time of the detection of an Event will be stored as a time stamp if the Event has already occurred before the system starts.



10. Error Responses in BACnet Communication The following PDUs will be returned if processing in response to the requests of BACnet client cannot be executed. ErrorPDU

11. Detailed Explanation of Objects

11.1. Common to All Objects Objects related to the air conditioner in communication are treated on the BACnet as described below. (1) Air Conditioner in Normal Communication

Other BACnet devices can access each object related to the air conditioner. (2) Air Conditioner Unconnected

It seems to other BACnet devices that no objects related to the air conditioner exist. Therefore, when the ReadProperty/WriteProperty service is received, the following ErrorPDU will be returned. Error class: OBJECT; Error type: UNKNOWN_PROPERTY

(3) Air Conditioner Communication Error Other BACnet device can access the objects related to the air conditioners, but the Present_Value Property will be

read in a value immediately before the communication error. The Reliability property value of each object is set to UNRELIABLE_OTHER. Whereas, the value will be set to

NO_FAULT_DETECTED while in normal communication, and the FAULT flag of the Status_Flags property will be set to TRUE.

A command executed while the system has a communication error will be sent to the air conditioner.



11.2. ON/OFF (Setting) Member number: 1 Object name: StartStopCommand_XXX (XXX: A/C group number) Object type: Binary Output Meaning: This object is used to give ON/OFF commands to the air conditioner. Present_Value property:

Remarks: (1) If there is an operation error, the Present_Value property will be set to ACTIVE regardless of whether the air

conditioner is in operation or not. (2) The IN_ALARM flag of the Status_Flags property of the ON/OFF status object will not be set to TRUE if the air

conditioner has an error. To detect the occurrence of errors, always refer to the value of the Alarm Sign object.



11.4. Alarm Sign Member number: 3 Object name: Alarm_XXX (XXX: A/C group number) Object type: Binary Input Meaning: This object is used to monitor the Normal/Error status of the air conditioner. Present_Value property:

ACTIVE: Error INACTIVE: Normal

Remarks: (1) This object supports the Intrinsic Reporting function. When the Present_Value property changes, the corresponding

Event will be transmitted, provided that the Event has been registered. (2) Detailed information is set for the following properties.

Time_Delay property: No delay for error notification is permitted (the time is fixed at 0) and nothing can be written. Notify_Type property: Event notification is fixed at ALARM. Event_Time_Stamps property: It represents the time of occurrence (To-OFFNORMAL)/restoration

(To-NORMAL). Indefinite time will be set if an Event has not occurred yet. If an Event has occurred, the time of the Event being detected will be set at the rising edge. If power supply to the system fails, the time will be fixed at the rising edge.

(3) An error is a state of the air conditioner not being operated due to trouble, but other troubles such as an alarm or warning are not considered an error.

(4) To stop the error sign of the air conditioner in which an error has occured, the STOP command should be executed. It does not mean the air conditioner has been returned to a normal state and an error will occur if the RUN command is executed again.

(5) A failure code is set using two ASCII characters specified by DAIKIN for the Description property.

11.5. Error Code Member number: 4 Object name: MalfunctionCode_XXX (XXX: A/C group number) Object type: Multistate Input Meaning: This object is used to monitor the details of the error status when the air conditioner has an error. Present_Value property:

Remarks: (1) The air conditioner features two airflow rate settings for both Cooling and Heating operations. (2) The notification of airflow rate is merely to return the set airflow rate at the time of notification and has no

relationship with ON/OFF status of the air conditioner. (3) Some of the air conditioners have three airflow rate settings, but the Present_Value property will be set to either

Weak or Strong even if the actual airflow rate is set to Medium on the handheld remote controller.



11.10. Measured Room Temperature Value Member number: 9 Object name: RoomTemp_XXX (XXX: A/C group number) Object type: Analog Input Meaning: This is used to monitor the room temperature detected by the air conditioner. The room temperature monitored

by the air conditioner fluctuates to a certain extent according to the place where the sensor is installed. Present_Value property:

Room temperature detected by the air conditioner. Remarks:

(1) The unit will be °C and the valid range is between −10°C and +50°C. (2) When COV registration is made, the COV_Increment property is fixed at 1.0 and no value can be written.

The COV will be reported the moment a temperature change of at least 1°C is detected. When a temperature change of at least 1°C is detected after that, the next COV will be reported.

(3) This object supports the Intrinsic Reporting function, thus making higher and lower limit monitoring possible. When the room temperature exceeds the set higher and lower limits, the corresponding Event will be reported if the Event has been registered. The Event is reported in accordance with the BACnet rules.

(4) Higher and lower limit monitoring information is set for the following properties. High_Limit property: The higher limit monitoring value. The default value is +80.0. The value can be overwritten.

The new value will be saved 5 seconds after the value is written. Low_Limit property: The lower limit monitoring value. The default value is −80.0. The value can be overwritten.

The new value will be saved 5 seconds after the value is written. Deadband property: The dead zone. The default value is +5.0. The value can be overwritten. The new value will

be saved 5 seconds after the value is written. Time_Delay property: No delay for error notification is permitted (the time is fixed at 0) and nothing can be

written. Notify_Type property: Event notification is fixed at ALARM. Event_Time_Stamps property: It represents the time of occurrence (To-OFFNORMAL)/restoration

(To-NORMAL). At the rising edge:

Indefinite time will be set if an Event has not occurred yet. If an Event has occurred, the time the Event was detected will be set at the rising edge.

If power supply to the system fails, the time will be fixed at the rising edge. (5) If the air conditioner does not have a room temperature sensor, the Present_Value property will be set to 0.0°C. (6) When the room temperature sensor is disconnected, the Reliability property will be set to NO_SENSOR and FAULT

flag of the Status_Flags property will be set to TRUE. The Present_Value property will keep on hold the previous value.



11.11. Set Room Temperature Value Set Room Temperature Value Member number: 10 Object name: TempAdjest_XXX (XXX: A/C group number) Object type: Analog Value Meaning: This object is used to set the room temperature for the air conditioner. Present_Value property:

The set temperature for the air conditioner Remarks: (1)

(2)

(3)

(4)

The unit will be °C. The possible set range varies according to the type of indoor unit or outdoor unit. If the air conditioner is a VRV model, the approximate set temperature range for cooling is between 20°C and 35°C and that for heating is between15°C and 30°C. When COV registration is made, the COV_Increment property will be fixed at 1.0 and no value can be written. The COV will be reported the moment a temperature change of at least 1°C is detected. When a temperature change of at least 1°C is detected after that, the next COV will be reported. The possible higher and lower limits vary depending on the type of air conditioner and the mode in which the air conditioner is presently operating. If a value outside the limits is set, the value will be commanded to the air conditioner, but the air conditioner will limit the value within the predetermined higher and lower limit range. The air conditioner has set temperatures for both cooling and heating. When changing the operating mode as well as the set temperature, the operating mode should be changed first and the set temperature next. For example, in cases of changing from the current set temperature of 28°C in cooling mode to 20°C in heating mode, if the temperature is set to 20°C first and then operation mode is changed from cooling to heating, the set cooling temperature does change to 20°C for the moment but the heating temperature will be set to the temperature that the air conditioner has been kept internally, instead of the desired temperature (20°C).



11.12. Filter Limit Sign Member number: 11 Object name: FilterSign_XXX (XXX: A/C group number) Object type: Binary Input Meaning: This object is used to monitor the used-up state of the filter of the air conditioner. Present_Value property:
